These days I retorqued the propellers on my Mercury Bravo III outdrive. I have carried out this quite a few occasions and it was not tough, but it was a suffering as I had to do it in the h2o, with waves slapping at me all the time. The handbook claims to test the propellers each individual twenty hours and retorque as needed. I do not adhere to this recommendation, but I think my neighbors have not carried out this in twenty decades, not twenty hours. Okay, that is an exaggeration, but how significantly is genuinely needed? The identical factor could be said about a number of other duties.
